Glycemic control and atrial fibrillation: an intricate relationship, yet under investigation

Atrial fibrillation (AF) and diabetes mellitus (DM) constitute two major closely inter-related chronic cardiovascular disorders whose concurrent prevalence rates are steadily increasing. Although, the pathogenic mechanisms behind the AF and DM comorbidity are still vague, it is now clear that DM precipitates AF occurrence. DM also affects the clinical course of established AF; it is associated with significant increase in the incidence of stroke, AF recurrence, and cardiovascular mortality. The impact of DM on AF management and prognosis has been adequately investigated. However, evidence on the relative impact of glycemic control using glycated hemoglobin levels is scarce. This review assesses up-to-date literature on the association between DM and AF. It also highlights the usefulness of glycated hemoglobin measurement for the prediction of AF and AF-related adverse events. Additionally, this review evaluates current anti-hyperglycemic treatment in the context of AF, and discusses AF-related decision-making in comorbid DM. Finally, it quotes significant remaining questions and sets some future strategies with the potential to effectively deal with this prevalent comorbidity. © 2022, The Author(s)

Clinical outcomes in patients with atrial fibrillation treated with digoxin, according to the presence of heart failure: Insights from the MISOAC-AF trial

Background: Digoxin is widely used in atrial fibrillation (AF) and heart failure (HF). However, current evidence regarding its association with clinical outcomes is conflicting. Aim: To investigate the relationship between digoxin therapy and adverse outcomes in patients with AF, with or without HF, in a contemporary AF cohort. Methods: We performed a retrospective analysis of data from 698 patients, who were followed over a median of 2.5 years. The primary outcome was all-cause mortality and the secondary outcome was all-cause hospitalization, in a time-to-event analysis. Propensity scores were used to derive matched populations, balanced on key baseline covariates. To limit potential confounding, inverse probability of treatment weighting (IPTW) analysis was performed. Results: Among patients with HF, 39 (10.5%) were administered digoxin at baseline, whereas 331 (89.5%) were not. Digoxin administration was not associated with an increased risk of death (hazard ratio (HR) in the digoxin group, 1.21; 95% Confidence Interval (CI), 0.69 to 2.13, p = 0.50) or hospitalization of any cause (HR 1.15; 95% CI, 0.67 to 1.96; p = 0.60). Among patients without HF, 11 (3.5%) were administered digoxin, with neutral effects on all-cause mortality (HR: 3.25; 95% CI, 0.98 to 10.70), p = 0.06) and all-cause hospitalization (HR, 1.15; 95% CI, 0.67 to 1.96, p = 0.60). Qualitatively, consistent results were observed using IPTW. Conclusions: Among patients with AF, digoxin administration was not associated with an increased risk of death and hospitalization for any cause, irrespective of HF status. © 2022 Hellenic Society of Cardiolog

Prison escape and its political imaginary in times of political crisis : Tunisia, 2011–2016

International audienceIn 2011, during and after the revolutionary events in Tunisia, over a third of the total prison population escaped. These widespread jailbreaks could have been a symbol of emancipation from an abusive state power; but in Tunisia they instead came to represent the threat of criminal destabilization, and rumors of conspiracies against the democratic movement. Beyond the anecdotal dimension of these unusual events, this chapter analyzes the changing meanings of mass prison escapes in times of political transition, as they can be interpreted as part of liberatory moves, or reframed in a security-oriented political imaginary fueling more punitive policies

Optimizing the noninvasive ventilation pathway for patients with amyotrophic lateral sclerosis/motor neuron disease: a systematic review

Objective: To systematically review quantitative and qualitative literature on optimal provision of noninvasive ventilation (NIV) for patients with amyotrophic lateral sclerosis/motor neuron disease (MND). Methods: A systematic search of electronic databases, together with supplementary search methods was used to identify relevant literature from the last 20 years. Studies of any empirical design with an English abstract were eligible for inclusion. Data from documents meeting our criteria were extracted and synthesized using narrative and thematic synthesis. A patient pathway of care model was used to integrate data and provide a process perspective to the findings. Results: While the importance of individualizing care was highlighted, factors optimizing use for all patients include: specialized multi-disciplinary team service provision; determining need using respiratory function tests in addition to symptom report; providing adequate information for patients and their family; paying attention to the role of carers in decision-making; adequately managing secretions; considering the most advantageous place of initiation; optimizing the interface, machine mode, and settings for patient comfort and effectiveness; providing supportive interventions where appropriate; regular monitoring and adjustment of settings; and providing opportunities for ongoing discussion of patient wishes. Conclusions: Optimizing use of NIV in people with MND requires consideration of multiple factors as part of a process throughout the patient pathway. Current guidelines predominantly focus on the initiation of NIV and may underplay psychosocial factors. We have made evidence-based recommendations for each step in the pathway, which may help improve optimal uptake, usage, quality of life, and survival outcomes in patients with MND
